Lighting device for generating artificial light in passenger waiting area, has electric switching unit for linking presettable alternating voltage signals to power supply circuit for generating alternating current signals

摘要

The lighting device (1) has an electrical power supply circuit, lighting units (7) and a direct current electric power source (8), where presettable alternating voltage signals are linkable to the power supply circuit for generating alternating current signals corresponding to photon modulated artificial light by using an electric switching unit (13). The alternating voltage signals are linkable to electrical output signals of a sound carrier playback device that is a compact disk player (18) or a Motion picture expert group-one audio layer-three (MP3) player.
